The plot has thickened in the mystery of the September lane closures at the George Washington Bridge.

Christie appointees at the Port Authority of New York and New Jersey initially said that the agency was conducting a traffic study. Fort Lee mayor, Mark Sokolich, countered that the cones went out as a punitive measure after he declined to endorse the governor for re-election.

Last month, the drama heightened when two of Christie's top officials at the Port Authority, Bill Baroni and David Wildstein, abruptly resigned.

During a dramatic hearing conducted by Assemblyman John Wisniewski (D-Middlesex), George Washington Bridge director, Robert Durando was silent when asked if there was a "culture of fear" at the Port Authority.

Now, it appears that the scandal's tendrils reach deep into Trenton. Stay tuned for more updates. In the meantime, here is a 'Bridgegate' primer.
